Details:

Since R2016b, Matlab has helper functions to rotate the tick labels:
https://www.mathworks.com/help/matlab/ref/xtickangle.html
acting as wrappers around the XTickLabelRotation and XTickLabelRotationMode
properties of axes:
https://www.mathworks.com/help/matlab/ref/matlab.graphics.axis.axes-properties.html#budumk7-XTickLabelRotation

XTickLabelRotation is available in Octave but unused, while
XTickLabelRotationMode would still need to be added (and allowed to take
values "auto" and "manual").

I attach a possible implementation of xtickangle.m. When writing the help
text, I came across xticklabels.m which is very similar: I could rewrite
xtickangle.m to use a similar layout (with switch/endswitch). Given
xtickangle(), ytickangle() and ztickangle() are nearly identical, would it be
useful to have them call a generic __tickangle__()?

Even if the actual rotation of the tick angles is not yet implemented in
Octave, having these functions in place would contribute to Matlab
compatibility as it would replace a crash with a no-op.
